Here’s You Answer  

You either came across as a p r i c k in the interview or there were a certain number of slots to be filled and and a certain number, plus one, of interviewees and you were the highest qualified and therefore the least likely to not do as you were told, the most likely to b*tch and complain and the most likely to call out somebody up the chain when they told you to do something unsafe or illegal.

Glad I could clear things up for you.
